Description

Technical field:

[0001] The utility model relates to the technical field of lithium battery processing, and more specifically to an auxiliary tooling for assembling blade battery cores. Background technology:

[0002] When assembling existing blade cells, it is necessary to install an insulating sheet between two adjacent blade cells, then stack them front to back and align them, and then tie fiber tape around the outside to fix them. In order to facilitate the tying of the cells, the entire process is generally performed after being placed on a rotating table, so that the cells can be rotated easily.

[0003] However, the upper platen of the existing rotating table can rotate but cannot be fixed. That is, in certain usage situations, such as when multiple battery cells need to be placed on the upper platen and pressed against each other in a front-to-back alignment, it is hoped that the upper platen will not rotate. However, the current upper platen cannot be fixed. Therefore, when multiple battery cells are placed on the upper platen and pressed against each other in a front-to-back alignment, the upper platen will often be rotated, affecting the alignment operation, increasing the difficulty, and affecting the assembly efficiency. Utility model content:

[0021] For example, see Figures 1 to 6 As shown, an auxiliary tool for assembling blade cells includes an operating platform 1000. A bottom circular counterweight 10 is placed on the top plate of the operating platform 1000. A vertical rotating shaft 20 is fixed to the middle of the top surface of the bottom circular counterweight 10 (which can be welded or bolted. In this embodiment, it is welded. The bottom circular counterweight 10 is an iron block, which is heavy and can prevent it from tipping over). The top of the vertical rotating shaft 20 is movably connected to a circular rotating plate 30 via a bearing. The circular rotating plate 30 is an insulating plate.

[0022] An auxiliary bending block 40 with a right-angle bend is installed on the top surface of the circular rotating plate 30. The auxiliary bending block 40 is also made of insulating material. The left side walls of the multiple blade batteries 100 to be processed are close to the inner side walls of the side beams extending forward and backward of the auxiliary bending block 40, and the front wall surface of the frontmost blade battery cell 100 is pressed against the rear wall surface of the transverse beam in front of the auxiliary bending block 40.

[0023] The auxiliary bending block 40 includes a side beam, and a transverse beam extending laterally to the right is formed on the right side wall of the front end of the side beam;

[0024] A plurality of vertical positioning rods 41 are fixed to the bottom surfaces of the side beams and the transverse beams. The vertical positioning rods 41 are inserted into corresponding vertical through holes 31 formed on the top surface of the circular rotating plate 30 .

[0025] An elastic retaining sleeve 32 is fixed to the inner side wall of the vertical through hole 31. The vertical positioning rod 41 is inserted into the corresponding elastic retaining sleeve 32, and the outer side wall of the vertical positioning rod 41 is pressed against the inner side wall of the corresponding elastic retaining sleeve 32. The elastic retaining sleeve 32 can enhance the connection between the vertical positioning rod 41 and the circular rotating plate 30.

[0026] Furthermore, a plurality of positioning slots 11 are formed on the outer wall of the bottom circular counterweight block 10, and the top surface of the positioning slots 11 extends out of the top surface of the bottom circular counterweight block 10. A connecting block 33 is fixed to the bottom surface of the edge of the circular rotating plate 30, and an elongated positioning block 34 is movably connected to the connecting block 33 through a hinge shaft, and the lower part of the elongated positioning block 34 is inserted into one of the positioning slots 11.

[0027] A permanent magnet block 12 is fixed on the inner side wall of the positioning slot 11 , and the lower side wall of the elongated positioning block 34 is pressed against the corresponding permanent magnet block 12 and is adsorbed and fixed to the permanent magnet block 12 .

[0028] All the positioning slots 11 are evenly distributed on the outer side wall of the bottom circular counterweight 10 with the central axis of the bottom circular counterweight 10 as the center.

[0029] Furthermore, a connecting piece 50 is fixed to the outer wall of the circular rotating plate 30 corresponding to the elongated positioning block 34. Extensions 51 are formed on the left and right sides of the bottom surface of the connecting piece 50. The top surfaces of the two extensions 51 are fixed to the bottom surface of the circular rotating plate 30. A slot 52 is formed between the two extensions 51. The bottom end of the elongated positioning block 34 cooperates with the slot 52.

[0030] A limiting through hole is formed in the middle of the bottom end of the elongated positioning block 34, and a screw through hole is formed on the inner wall of the extension part 51 on one side of the slot 52. The ball plunger 1 is screwed into the screw through hole, and the spherical part of the ball plunger 1 extends out of the inner wall of the corresponding extension part 51 and corresponds to the limiting through hole.

[0031] The bottom end of the elongated positioning block 34 is formed with a downwardly extending protrusion to facilitate manual manipulation of the protrusion to achieve downward or upward flipping of the elongated positioning block 34 .

[0032] When this embodiment is in use, the vertical positioning rod 41 of the auxiliary bending block 40 can be inserted into the corresponding elastic clamping sleeve 32, and the outer wall of the vertical positioning rod 41 is pressed against the inner wall of the corresponding elastic clamping sleeve 32 to fix the auxiliary bending block 40. Then, the blade battery cells 100 to be assembled and the insulating sheet are placed at intervals, such as the front wall surface of the first blade battery cell 100 is pressed against the rear wall surface of the transverse beam of the auxiliary bending block 40, and the left side wall of this blade battery cell 100 is pressed against the inner wall of the side beam. Then, the insulating sheet is pressed against the rear wall surface of the first blade battery cell 100. The left side wall is close to the inner wall of the side beam, and then the front wall of the second blade battery cell 100 is pressed against the insulating sheet in front, and the left side wall is pressed against the inner wall of the side beam. Then, the blade batteries 100 and the insulating sheets are placed in sequence, wherein the bottom surfaces of all blade batteries 100 and insulating sheets are pressed against the top surface of the circular rotating plate 30. After the placement and stacking are completed, the outer wall of the rectangular body composed of all insulating sheets and blade batteries 100 is tied with fiber tape. When tying, the circular rotating plate 30 can be rotated to make the rectangular body rotate, so that the fiber tape can be tied very conveniently.

[0033] When stacking the insulating sheet and blade cells 100, the lower portion of the elongated positioning block 34 can be inserted into one of the positioning slots 11. The lower sidewall of the elongated positioning block 34 presses against the corresponding permanent magnet block 12 and is fixed by attraction thereto, thereby preventing the circular rotating plate 30 from rotating, facilitating the stacking and assembly of the insulating sheet and blade cells 100.

[0034] When tying, the elongated positioning block 34 can be placed above so that its bottom end is in the slot 52. The spherical part of the ball plunger 1 extends out of the inner wall of the corresponding extension part 51 and is embedded in the limiting through hole to fix the elongated positioning block 34. At this time, the circular rotating plate 30 can rotate together with the rectangular body above, which is convenient for tying the fiber tape.

[0035] Finally, it should be noted that the above embodiments are merely representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and is susceptible to numerous variations. Any simple modifications, equivalent variations, and modifications to the above embodiments based on the technical essence of the present invention shall be deemed to fall within the scope of protection of the present invention.
